[RFA/RFC] Prec multi-thread support [3/4] thread.c

[Hui Zhu <teawater@gmail.com>]

1. Move thread_state to gdbthread.h because record target need get the
status of each thread.  Sometime, GDB will not remove the thread entry
when it exit.
2. record_is_waiting is to flag that mean this thread is still
running.  I will introduce in next mail.

	gdbthread.h (thread_state): New enum.
	(thread_info): Add record_is_waiting.
	thread.c (thread_state): Deleted.
